Thank you very much for your help Bill. We didn't witness the actual egg laying event, but these nudibranchs were on this hydroid at this approximate point for about 10 days from the time we found them. The eggs were not there when we found them, and were there when I went back this time to take a look. Fairly strong circumstantial evidence?

Dear Tony,
I'm afraid your evidence is not that strong. It's equally possible that something else visited when you were not there and deposited the egg mass. I suspect the egg mass is very large for the size of your Doto. A small animal like Doto would attach its egg mass firmly to the substrate or some solid surface. Your egg mass seems to be attached only at odd intervals. I can't see how a Doto of this size could crawl between the attachment points while it was laying the egg mass. It would need to crawl over a solid surface. I suspect the eggs were layed by a much larger animal which could stretch out from one algal 'branch' to the next - but that's only my considered opinion, I could be quite wrong.
Cheers,
Bill Rudman
